VAPOR-BURN ER.

SPECIFICATION forming part of Letters Patent No. 519,830, dated May 15, 1894.

Application l d December 2,1892. Serial No.453,819. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE W. BILLINGS, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Vapor-Burners, of which the following is a full, clear, and complete descrip- My invention relates to a vapor burner havng an annular perforated shield surmounting a perforated combustion chamber, a nonperforated shield within saidperforated shield and resting on. the flange of a cup or spreader which depends into said perforated chamber, air tubes entering the interior of the non perforated shield from the exterior of the perforated combustion chamber, two supply pipes from the tank, one of which connects, through the medium of an ordinaryneedle valve with the perforated combustion chamber and the other with the sub-burners through a stand pipe and suitable needle valves arranged beneath and in contact with said combustion chamber, a fender interposed between the needle valve and combustion chamber for absorbing the heat which would otherwise be conducted from the burner to the needle valve and vaporize the fuel in said valve.

The object of the invention is to provide a self generating burner and one that will also generate gas for any number of sub-burners.

That the invention may be seen and fully understood, reference will be had to the following specification and annexed drawings forming part thereof.

Figure 1 is an elevation of my improved burner showing the double connection with the tank, the shields and cap of the burner re moved and their positions indicated by dotted lines, the sub burner pipes not shown. Fig. 2 is a view of the burner detached. Fig. 3 is a plan View with shields removed showing two the flange 3 up through said flangeand form supports on which the flange 5 of the non perforated cup or spreader 6 rests, said flange 5 being provided with air tubes 7 in open connection with the tubes 4. The liquid fuel from the tank 8 is admitted to the two supply pipes 9 and 10 by an ordinary valve 11. The

pipe 9 connects with the needle valve 12 Figs. 1, 3 and 4 which is in direct connection with the combustion chamber 1 through the pipe 13 and conduit 14 Fig. 8. The pipe 10 is in connection withthe needle valves 15 and 16 through the stand pipe 17, said needle valves 15 and 16 are arranged beneath and in contact with the combustion chamber 1 and supply the sub-burners through the pipes 18 and 19. The supply of fuel for the sub burners being through the pipe 10 and that for the main burner through the pipe 9, prevents the lowering of the pressure in the main burner when the sub burners are lighted owing to the pressure in the two pipes 9 and 10 being equal. An annular perforated shield 20 Fig. 8 (shown dotted in Fig. 1) rises from the outer edge of the flange 3. Within the shield 20, and rising from the flange 5 is a non-perforated shield 21, the upper terminal of which is covered, and just beneath the cover of said non perforated shield is a series of notches or slots 22 Figs. 7 and 8. The orifice in the needle valve 12 is adjusted to theright size to supply the required amount of liquid fuel for combustion in the chamber 1, and preventing any overflow. The flame from the combustion chamber is impinged upon the under side of the depending cup 6 and passes up over the flange 3, where it is supplied with oxygen from the perforations in said flange and passes up within the annular chamber formed by the perforated shield 20 and the non perforated shield 21, upon reaching the top of said shield 21 it is supplied with more oxygen,as the exterior air enters the tubes 4, passes into the interior chamber is impinged on the top and forced out of the slots 22, thus increasing the heat at the point where it is most essential. An outside shield 23 is provided to protect the flame from sudden or unequal drafts, said outside shield being surmounted by a suitable cap 24 for distributing the flame.

The needle valves and 16 being in contact with or a part of the same casting as the combustion chamberl become heated from the flame in said chamber and when opened will supply vapor to the sub-burners through the pipes 18 and 19.

A fender 25 Fig. 1 is interposed between the main burner and the needle valve 12. The liquid fuel is kept cool in said needle valve by the interposition of the fender, which absorbs and radiates the heat conducted from the burner by the pipe 13, the liquid fuel is therefore prevented from vaporizing at the needle valve 12 thus allowing the orifice in said valve to be made just the right size to I furnish the required amount of fluid to the main burner. I claim 1. In a vapor burner, a combustion-chamher having perforated walls provided with a flange, a non-perforated shield forming an interior chamber, the air-tubes 4 extending from the exterior of said combustion chamber through said flange to said interior chamber, and a cup depending into the combustionchamber, said cup having a, flange with airtubes therein in open connection with said tubes 4, in combination with a perforated shield rising from the flange of the combustion-chamber and circumscribing said nonperforated shield, in the manner substantially as and for the purpose set forth.

2. In a vapor burner, needle valves for supplying sub burners, arranged beneath and in contact with the combustion chamber of the main burner, said needle valves being supplied through a pipe independent of the pipe supplying the main burner, whereby the gas for the sub-burners is generated by the main burner without decreasing the pressure in said burner substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE W. BILLINGS.
